Three - dimensional distribution of geomagnetic energy in the earth ' s interior and its secular variations 地磁場(chǎng)能量在地球內(nèi)部的三維分布及其長(zhǎng)期變化
Three - dimensional distribution and histological studies of extraocular muscle pulley in human orbit 人眼外肌滑車(chē)在眼眶立體空間的分布和組織形態(tài)學(xué)研究
The technique is to utilise other supplementary information to make an indirect estimate of the three - dimensional distribution of various meteorological elements ( such as air pressure , wind and moisture ) around the centre of the tropical cyclone 技巧是利用其他輔助資料來(lái)推算各類氣象要素(包括氣壓、風(fēng)和水氣)在熱帶氣旋中心附近的三維分布,作為電腦預(yù)報(bào)模式的初始條件。
By the test of three - dimensional distribution , form character , rotating frequency and magnetic field intensity of rotating magnetic field , it showed that the magnetic field produced is a highly rotating magnetic field and mainly distribute on welding arc region , rotating frequency and magnetic intensity can be regulated through excitation power source 通過(guò)對(duì)產(chǎn)生磁場(chǎng)的空間分布,形態(tài)特征,以及旋轉(zhuǎn)頻率和場(chǎng)強(qiáng)大小的測(cè)試證明該磁場(chǎng)是一個(gè)高速旋轉(zhuǎn)的磁場(chǎng)空間,而且磁場(chǎng)主要集中分布在焊接電弧區(qū)域內(nèi),磁場(chǎng)的旋轉(zhuǎn)頻率和場(chǎng)強(qiáng)大小都可以通過(guò)勵(lì)磁電源進(jìn)行良好調(diào)節(jié)。
